它是如何運作的？
檢查文章 (任何具有縮略圖支援的文章類型，包括頁面) 是否已經有與之關聯的特色圖片，如果沒有使用以下其中一種方法之一設置它：
動態為舊的已發佈的文章，僅在需要在前端顯示它們時才設置特色圖片。這意味著當訪問者加載需要顯示特色圖片的頁面時，特色圖片會被設置 (僅第一次)。
對於新的內容，特色圖片在發佈過程中設置。
沒有選項頁面可供設置，只需安裝並啟用即可。
如果您想要排除某些文章類型(例如頁面)，您可以使用過濾器來實現。詳細信息請參閱常見問題解答 。
Easy Add Thumbnail 不會在您的 WordPress 數據庫中添加任何插件數據。它只是將 _thumbnail_id 資料夾與要用作特色圖像的附件的 ID 相關聯(與您手動設置時相同)。
因此需要至少附加/上傳一張圖片至文章。如果沒有將任何圖片附加到文章中，則此外掛不能幫助您。
Easy Add Thumbnail 沒有任何關於您的特色圖片如何 / 何時 / 在哪裡顯示於您的網站上，特色圖片於您的網站上的顯示完全受您的佈景主題控制，包括大小、位置，是否顯示… 等。
需求
WordPress 4.7 或更高版本。
PHP 5.6 或更高版本。

原文外掛簡介
NOTE: This plugin functionality is guaranteed by more than 10,000 active installs. But before installing this plugin bear in mind that its only purpose is to ADD the feature image ID to your post (in the same way that you would do using WP editor), it does not remove ANYTHING after deactivation.
Before asking for support please read FAQ and this support thread
How it works?
Checks if the post (any post type with thumbnail support, including pages) has already a featured image associated, and if not sets it using one of the following methods:
Dynamically, for old published posts, the featured images are set only when needed to show them in the frontend. This means that the featured image is set (only first time) when a visitor loads the page where it needs to be shown.
For new content, the featured image is set in the publishing process.
No options page to setup, simply install and activate.
If you want to exclude certain post type (e.g. pages), you can do it by using a filter. See FAQ for more details.
Easy Add Thumbnail doesn’t add any plugin data to your WordPress database. It simply adds the _thumbnail_id meta key with the ID of the attachment to be used as feature image (just the same that WordPress does when you set it manually).
Therefore it requires to have attached/uploaded at least one image to the post. If there’s not any image attached to the post, this plugin can’t help you.
Easy Add Thumbnail has not any control over how/when/where your featured image is displayed in your site, the display of the featured image in your site is TOTALLY controlled by your theme, this includes size, position, display it or not…
Requirements
WordPress 4.7 or higher.
PHP 5.6 or higher.
